Hello there

Do you only use Thunderbird? Does any other user have anything to do with this? can i ask you?

To check whether there was clearly an installation just for you and whether there is a copy of Thunderbird saved on your computer.

Clean with a tool, for example a hard drive cleaner.(or with a version from cccleaner ) Is there a second version of Thunderbird software present. Delete every profile of the old software or (and)delete software leftovers from the new installation if it is possible to do this.

I am the only User. the PC recently crashed and i Suppose there was an Update running in the back.

Hello there

Your installation together with your PC had a connection with your PC and the part of the Thunderbird software to be installed.

During or around the time your PC crashed, this update may have been interrupted from certain connections on your PC machine.

You have the backup. Your details can be requested again when you log in. Your account will continue to exist with the normal login details.

First you need to fix your computer from your crashed moment.

You cannot install Thunderbird software safely on a crashed PC.

How did the computer crashed? (It are two different things the crashed computer ,and the interrupted Software from Thunderbird.)

A sudden standstill of your Thunderbird version and/or software can be resolved by also starting up in safe mode if this is still possible after your software has not been completely installed.

I recommend to fix the pc first. After the repair of the tower pc . You can Reinstall the latest software of Thunderbird.

try scanning for antivirus and mall ware errors.

Thank you for the further information. I have yet not had the opportunity to try troubleshoot Mode for thunderbird. I hope to return to the PC on the weekend. Everything else runs perfectly, including Firefox. I will report back when I tried. Best regards.

Cache has nothing to do with updates.

https://support.mozilla.org/en-US/kb/thunderbird-software-update-failed previously cited should be a good starting point

If there is still a problem, then delete the Thunderbird program directory (not the profile directory) using Windows File Explorer.

I was trying to help this client out of his maybe broken(crashed) pc.

Oké cleaning up the cache is not a chosen option for this Thunderbird version. We keep that in mind.

Thank you.

The user isn't actually crashing.

1. Delete everything in %temp% 2. "Side by side" doesn't sound like a bug in Thunderbird. Check https://www.stellarinfo.com/blog/fix-windows-side-by-side-configuration-error/ 3. Delete directories with Thunderbird in the name from \Program Files\ and \Program Files (x86)\ 4. Install Thunderbird from https://www.thunderbird.net/en-US/

Is "unfinished" the exact English word used in "unfinished thunderbird update"?

Thanks for the further Information, Wayne Mery. For 1.: I ran Disk Cleanup on everything, so all temps should be gone. For2.: I will check that link For 3.: So I just delete the program folder? doesnt that make an uninstallation completely impossible? For 4.: I will try, but I fear just deleting the program folder will leave the program in the "system" and it will still be listed as an installed program producing the same error.

My Windows is in german, so I don't know the exact Word. I can just say that trying to uninstall the program or trying to install over the existing program produces an error akin to "thunderbird Update in progress/unfinished. restart PC to continue". after restart nothing changes.

1. 3 and #4 should be fine.

An install will replace everything that is needed for a future uninstall.
